I have found the following information in the "ialmnt5.inf" file I am just not sure what to change it to.

[NonEDIDMode_AddSwSettings]
HKR,, TotalDTDCount, %REG_DWORD%, 0 ; This shows number of DTDs to be used. ; 0-->Disable the feature.
;Following keys have 20 bytes (18 byte DTD + 2 Byte flags).

Change TotalDTDCount from "0" to "1"

Change DTD_1 to

66,21,50,B0,51,00,1B,30,40,70,36,00,75,F2,31,00,00,1E,37,01

Run setup.exe in the drivers directory.

Restart and 1360x768 should show up unless your laptop provider has explicitly prohibited it. If they have, we can try another one.

Hi Archibael

Thanks for your reply.I changed the INF file as shown below, ran setup, rebooted, tryed to change the res again but it did not give me any options larger than 1024X768 for the samsung monitor.

I would love it if there is something else we could try.

mj_stanton,

Yeah, it seems to me like Toshiba's one of those problematic vendors who turns off certain resolutions in the Video BIOS. I still don't get that, but whatever... you were on the right track with DTD_2, above, but what you needed was(for 1358x768):

66,21,4E,B2,51,00,1B,30,40,70,36,00,75,F2,31,00,00,1E,37,01

That ought to work.

Of course, if it doesn't, you should check the registry with regedit and make sure that all the DTD_x entries are populated with your DTD.

Thanks very much that worked great

YOU'RE MY HERO, archibael!

I've been searching for a solution since EVER!

Thank you very much =)

This post has the link to the original Wiki as well as some tools which can make it easier.

Hi, is there any way for someone to tell me how to make the Intel 945G default resolution to start and be 800x600.

and I use the igxp32.inf file.
